"IIIIIIIIIIIIIIIIIII/ Patented July 29, 1930 PATENT OFFICE ROBERT HOE,OI HYDE PARK, NEW YORK POWER UNIT Application filed August 85, 1927.Serial 110,215,829.

This application relates to a novel and improved power unit which may beemployed for a plurality of purposes. The invention will be bestunderstood from the following description, when taken in connection withthe accompanying drawing, in which I have shown an embodiment of theinvention, and

in which Fig. 1 is a horizontal sectional view through the gear casingof the invention;

Fig. 2 is a vertical sectional view through the casing shown in Fig. 1;

3 is a section on the line 33 of Fig. 2; an

F 4 is a view on a smaller scale showing on; form which the entireapparatus may ta e Referring now to the drawing in detail,

I have shown my invention as comprising a suitable base 1 which forms asupport for the unit. This base has mounted thereon a standard 2 uponwhich is slidably mounted a sleeve 3 to which is secured the casing 4.The sleeve and standard are provided with a plurality of holes 5 withinwhich may be received a pin 6 so as to adjustably support the sleeve inany one of a plurality of positions with respect to the base. The sleeve3 is made in two parts, one of which is rotatable with respect to the 0other. The lower part 7 is held against rotation with respect to thestandard 2 by any suitable means such as the pin 6, and the upper part 8is held in adjusted position on the part 7"by means of a latch 9 adaptedto engage in one of a plurality of notches n a flange 10 on the part 7.The above described apparatus exemplifies means for ad usting the unitboth vertically and rotatably with respect to the base upon which it issupported. The details of these means are better shown in my co-opendingapplication for washing machine, Serial No. 138,356. It is toberunderstood that I consider these means as mere ly exemplary, as othersuitable means may be employed.

Carried on the casing 4 is a suitable motor 11, the shaft 12 of whichmay be connected by a suitable belt to a pulley 13 upon a power shaft 14journalled in the casing. This shaft has a worm 15 meshing with a wormgear 16, secured to a rotatable shaft 17. At one end of this shaft it isprovided with a crank 18 to the end of which is pivoted a link 19 whichin turn is pivoted at its other end to an arm 20 secured to a rock shaft21. This rock shaft has an outlet from the casing which is exemplifiedby a bore 22 in a boss 23 on the casing. This bore is adapted to receivea sleeve 24 within which may be journalled a shaft 25 having coactingmeans 26 by which it may be clutched to the shaft 21.

The other end of the rotatable shaft 17 has an outlet from the casingindicated at 27, and this outlet may be used to operate a continuouslyrotating shaft such as that indicated at 28. This shaft 28 may ,bemounted in a suitable support exemplified by a gear box 29, omitted fromFig. 1, which may contain suitable gearing shown in dotted lines in Fig.2, connecting the shaft 28 with other 7 shafts 30 and 31. By this meansthere may be provided a plurality of shafts which operate from the shaft17 and rotate at different speeds, depending upon the gearing in the.box 29. .The box may be hinged at 32 to the casing and may be held inposition by a suitable latch 33, thus forming a detachable powertransmitting unit.

The shaft 17 has loosely mounted thereon two bevelled gears 34 and 35,between which is disposed a bevelled gear 36 which meshes therewith.Splined upon the shaft 17 is a collar 37 having clutch teeth 38 and 39which are adapted to be received in corresponding recesses in the hubsof the gears 34 and 35, respectively. The collar. may be slid lengthwise ofthe shaft by operation of a handle 40, which is operativelyconnected to the collar by means of a lever 41 having a pin 42 which Isreceived within a groove in the collar. By i i this means the clutchteeth may brought take place in either direction. The handle 40 isyieldingly held in position by means of a compression spring 45, whichyieldingly holds a pin 46 in any one of a plurality of notches 47. Thispermits'the shaft 17 to run idle or to be connected to the shaft 28 andto rotate it in either direction.

From the above it will be seen that I have devised a self-contained owerunit which may be conveniently emp oyed particularly for householdpurposes. One use to which the unit may. be put is the operation of awashing machine and it will beobvious that many other uses will be foundfor the unit. For example, one of the shafts 28, and 3i may be employedfor the support of a bufiing wheel for cleaning silver or for thesupport of a stone for sharpening knives. These uses are given only asexamples, however, as many other uses will suggest themselves.

1 As plainly shown in Figs. 1 and 2, the gear box forming the powertransmitting unit is mounted upon hinges in the form of pins received incars 48 on the gear box. The gear box may then be easily placed inosition on the pins and removed therefrom by a movement which isvertical in the form illustrated, and which is transverse to the lengthof the on the hinges into a position wherein the clutch elements 43 and44 cooperate to operatively connect the shafts 17 and 28. When in thisposition, it will be. noticed that movement of the box off the hingepins is prevented by engagementpf the clutch elements, these elementsoverlapping as plainly shown in the drawings. Movement on the is alsoprevented by means of the latch 33, this latch comprising an car 49which is dis d be tween the car 50 when the clutch elements are ingshaft mounted thereon, a device adapted tobe driven by said drivingshaft and coniprising a driven shaft, overlapping elepreventingmovementpof said ments on said shafts to form a dri connectiontherebetween, and a hinge a apted to support said device with saidshafts in operative position with respect each other, said hingecomprising cooperating members on said support and on said deviceseparable by a movement transverse to the length of said shafts.

2. In combination, a support having a driving shaft mounted thereon, adevice adapted to be driven by said driving shaft and comprising adriven shaft in alignment therewith, overlapping clutch elements on saidshafts to form a driving connection therebetween, and a hinge adapted tosup-.

support said device with said shafts inoperative position with respectto each other, said hinge comprising cooperating members on said supportand on said device separable by movement transverse to the length ofsaid shafts, a latch adapted to detachably hold sald device with theshafts'in said operative position, and adapted to prevent relativemovement between said hinge members when said shafts are in saidoperative position.

4. In combination, a power unit having a driving shaft, a device adaptedto be operated by said power unit and comprising a driven shaft,coacting clutch elements on said shafts, a hinge connecting said deviceto said unit and comprising two members, a hinge pin and a membercoacting therewith and brought into engagement with the pin by movementlengthwise thereof, and means hinge members with respect to each otherwhen said clutch elements are brought into cooperative relationship.

5. In combination, a power unit ha a horizontally disposed drivingshaft, ail d v ioe adapted to be operated by said power unit andcomprising a horizontally dispwed driven shaft, a hinge connecting saiddevice to said unit and comprising cooperating members on the unit andon the device separable by vertical movement 0f the device withrespectto the unit, coacting clutch elements on said shafts and adaptedto be brought into cooperative relation to each other with said sliaftsin alinement when said device is swung on said hinge, and cooperatingelements on the unit and device preventing vertical movement of thedevice on its hinge when said shafts are in operative position.

6. In combination, a power unit having a driving shaft, a device adaptedto be operated by said power unit and comprising a driven shaft, a hingeconnecting said device to said unit, aclutch to connect said shaftscomprising elements on each shaft, and means to so position said devicewith respect to the unit, as to render said clutch operative.
